Hey can someone help me with this question? Reggie was solving a system of equations. after manipulating them, he decides to add the two equations shown below together to eliminate the variable x. what property justifies this?

please show work :)

6x + 5y = 17
-6x + 2y = 4

thank you to anyone who helps me :)))

1/5^2 = 7.56/45

-232

step-by-step explanation:

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.
